All of his friends have been accounted for, but when Mr Leslie did not return to his student housing that night his family initially hoped he was among the injured still being seen in hospitals across Nice.

His father, 55, said: "We think he escaped the truck, but he could have been trampled.

"Our real frustration is how long it has taken to develop a list of the injured. It seems like something you would do immediately."

Posters with Mr Leslie's picture were plastered along the beach front and promenade as the family continued their desperate hunt for the student, a junior in UC Berkeley's College of Natural Resources.
